Echo: curl-7.69.1: security update to 7.69.1+e2

medium Tenable Self-Hosted Container Security Plugin ID 478460

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different
 backends for resolving host names, selected at build time. If it is built to use the synchronous resolver,
 it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this,
 libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore
 crash or otherwise misbehave. (CVE-2023-28320)

Solution

Update the curl-7.69.1 library and its related packages to version 7.69.1+e2 or later.
